Hi everyone name is Dave, I’m new to this forum and am a WRX owner. 2016 Premium with 60k on it. Recently did some bulb upgrades and sprung for the silver star ultras. Changed HB/LB Blinkers, and fog lights. Checking them out once complete and realized that the C Lights will not flash the amber color. Just stays solid white. I’m sure there may be something in these threads and if so can someone point it out please. If not any advice would be much appreciated. They both worked prior to the bulb replacement and I really hate to think that the bulbs need to be a special style. Please help thanks.
